Recent environmental and maintenance issues in the vicinity of the property have been documented through multiple 311 calls, particularly between 2023 and 2024. These incidents include recurring graffiti problems on public infrastructure (most recently in June 2024), tree-related issues affecting sidewalks (with one case still open as of June 2023), and various street maintenance concerns such as hazardous materials (2022), abandoned garbage (September 2023), and an encampment cleanup (May 2024).

A recorded fire incident consisting of a smoke detector activation with no actual fire occurred, though no injuries were reported. The building's location and history suggest ongoing challenges with public space maintenance and environmental issues in the immediate area, while the building itself has undergone some significant infrastructure improvements over the years.
